Filament spool spindle adaptor

I have designed this adaptor to clip onto regular filament spools with 60mm spindle holes. The adaptor allows the use of 8-10mm rods, or inserted mounted bearings to suit custom spool mounting configurations. In my case I use two attached bearings (mounted in two plugs which attach onto the ends of the adaptor) to hang from yokes on the side walls of a plastic dry box.
